Windows Defender is anti-virus software inbuilt in Windows 10 OS by default. While there are many controversial opinions about its reliability and capacity, security specialists unitedly agree upon the fact that Windows Defender, as an inbuilt tool, is a good idea because Windows OS gets installed with a powerful protection. However, people encounter lots of issues related to this anti-virus, for example, the error code Ox800706BB. This error message typically shows up when the PC user attempts to activate Windows Defender. It says: “An error has occurred in the program during initialization. If the problem continues please contact your system administrator. Error Code Ox800706BB.” Even though there are hundreds of people whose computers got struck by this bug, Microsoft has neither approved nor fixed it yet. However, people who could not launch Windows Defender managed to fix Ox800706BB error either by re-enabling it, deleting third-party anti-virus or changing Group Policies Settings. Before you start performing any fixes manually, we would strongly recommend you to check the system with a professional anti-malware/optimization tool, say Reimage. It will ensure that the system is not infected with malware and it’s not blocking Windows Defender now. Besides, it will check the system for corruption and damage, which may also be causing the Ox800706BB bug.

If you have already performed a system scan with Reimage or another professional optimization tool, but the scan results were not informative, you should try the following methods:

Method 1. Disable and enable Windows Defender

  • Using the left pane, navigate to the HKey_Local_Machine\Software\Policies\Microsoft\Windows Defender key.
  • Find DisableAntiSpyware key and delete its value. For this purpose, you have to double-click on the REG –DWORD and set its value to 0.
  • Then set its value to the one that was set before and check if the issue persists. Either way, DO NOT leave your OS unprotected.

Method 2. Remove third-party anti-virus

Are you using a third-party anti-virus? Windows Defender remains a default anti-virus tool in Windows 10 as long as the PC user does not install another third-party anti-virus/anti-malware tool.  Therefore, if you have installed another security tool some time ago, you should uninstall it completely in order to use Windows Defender service again.

Method 3. Change Group Policy Settings

Prevent websites, ISP, and other parties from tracking you

Private Internet Access is a VPN that can prevent your Internet Service Provider, the government, and third-parties from tracking your online and allow you to stay completely anonymous. The software provides dedicated servers for torrenting and streaming, ensuring optimal performance and not slowing you down. You can also bypass geo-restrictions and view such services as Netflix, BBC, Disney+, and other popular streaming services without limitations, regardless of where you are.

A VPN is also crucial when it comes to user privacy. Online trackers such as cookies can not only be used by social media platforms and other websites but also your Internet Service Provider and the government. Even if you apply the most secure settings via your web browser, you can still be tracked via apps that you are connected to the internet. Besides, privacy-focused browsers like Tor is are not an optimal choice due to diminished connection speed.

Therefore, to stay completely anonymous and prevent the ISP and the government from spying on you, you should employ Private Internet Access VPN. It will allow you to connect to the internet while being completely anonymous, prevent trackers, ads, as well as malicious content. Most importantly, you will prevent the illegal surveillance activities that NSA and other governmental institutions are performing behind your back.


Recover your lost files quickly

Unforeseen circumstances can happen at any time while using the computer: it can turn off due to a power cut, a Blue Screen of Death (BSoD) can occur, or random Windows updates can decide to reboot the machine when you went away for a few minutes. As a result, your schoolwork, important documents, and other data might be lost.

Additionally, you might also be attacked by malware that can corrupt your Windows or encrypt files with a robust encryption algorithm, and ask for a ransom in Bitcoin for the decryption tool. Cybercriminals might not deliver what they promised, however, so it is better to attempt alternative file recovery methods that could help you to retrieve at least some portion of the lost data.

Data recovery software is one of the options that could help you recover your files. Once you delete a file, it does not vanish into thin air – it remains on your system as long as no new data is written on top of it. Data Recovery Pro is recovery software that searchers for working copies of deleted files within your hard drive. By using the tool, you can prevent loss of valuable documents, school work, personal pictures, and other crucial files.
